Pastor Bryan Miller
Children’s Ministry Pastor
Pastor Miller was born in Canton, Ohio, but considers Chandler, Arizona to be his hometown. He distinctly remembers accepting the Lord as his Savior at age 6: “I was on top of my bunk bed, wearing Mickey Mouse pajamas. I had just spent a week at day camp. A message from camp held onto my heart, and I knew I needed to ask Jesus to be my Savior. So, right there in my bed I prayed and asked the Lord to save me from my sins.” This experience undoubtedly influenced Bryan’s later decision to work in children’s ministry. He received a B.A. in Pastoral Studies from International Baptist College and Seminary and became Children’s Pastor at Tri-City Baptist Church in 1996, though he had already been serving in their children’s ministry for ten years.
